The Architecture of Errors: From Universal Impossibility to Patch-Local LLM Reliability

arXiv:2605.30628v1 Announce Type: cross Abstract: Universal LLM reliability is not a finite-library problem: across all possible tasks, tools, schemas, knowledge sources, and evaluator expectations, new intervention-distinguishable failure modes can appear without bound, so no finite intervention dictionary can guarantee bounded residual error for every such mode. But deployed systems do not operate over the whole universe. They operate inside operationally bounded patches (legal review, medical RAG, code repair, customer-support agents, contract extraction) with recurring tasks, schemas, tool

Why this matters
Why now

This paper highlights a critical challenge for the rapid deployment of AI systems, particularly LLMs, as real-world applications expose the limitations of universal reliability approaches.

Why it’s important

It provides a more realistic framework for achieving reliable LLMs within bounded operational contexts, which is crucial for enterprises and governments seeking to integrate AI into critical functions.

What changes

The focus shifts from seeking universal LLM reliability to understanding and managing 'patch-local' or domain-specific reliability through targeted interventions and finite-library solutions.
